CROSS-REFERENCE TO RELATED APPLICATIONS

Kalanchoe Plant Named KJ 2003 0762; Knud Jepsen, Applicant; disclosed in a U.S. Plant patent application Ser. No. 11/146,204.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana, and hereinafter referred to by the name ‘KJ 2003 0785’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in Hinnerup, Denmark. The objective of the breeding program was to create new freely-flowering Kalanchoe cultivars with large flowers, numerous petals per flower, attractive flower coloration and excellent postproduction longevity.

The new Kalanchoe originated from a cross-pollination made in Hinnerup, Denmark, of the Kalanchoe cultivar Celine, disclosed in U.S. Plant patent application Ser. No. 10/654,563 now abandoned, as the female, or seed, parent with the Kalanchoe cultivar KJ 2001 1858, not patented, as the male, or pollen, parent. The new Kalanchoe was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Hinnerup, Denmark.

Asexual reproduction of the new Kalanchoe by terminal cuttings at Hinnerup, Denmark, by the Inventor, has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar KJ 2003 0785 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repreatedly observed and are determined to be the unique characteristics of ‘KJ 2003 0785’. These characteristics in combination distinguish ‘KJ 2003 0785’ as a new and distinct cultivar:

-   -   1. Upright plant habit.     -   2. Dark green-colored leaves.     -   3. Orange-colored double flowers with more with 20 petals per         flower.     -   4. Excellent postproduction longevity.

Plants of the new Kalanchoe differ primarily from plants of the parent cultivars in petal number and petal coloration.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe cultivar KJ 2003 0762, disclosed in a U.S. Plant patent application Ser. No. 11/146,204. Plants of the new Kalanchoe differ from plants of the cultivar KJ 2003 0762 in petal size and coloration.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe cultivar KJ 2002 0521, disclosed in U.S. Plant Pat. No. 16,088. Plants of the new Kalanchoe differ primarily from plants of the cultivar KJ 2002 0521 in petal number and petal coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe. The photographs were taken under diffuse natural light conditions on a sunny day at approximately noon in Hinnerup, Denmark.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering potted plant of ‘KJ 2003 0785’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the photographs and for the following observations and measurements were grown in Hinnerup, Denmark, under commercial practice in a glass-covered greenhouse for about ten to eleven weeks after the start of short day/long night photoperiodic treatment with average temperatures of 20° C. Plants used in the description and photographs were not pinched. Unless otherwise specified, the leaf description represents leaves from a vegetative plant.

-   Botanical classification: Kalanchoe blossfeldiana cultivar KJ 2003     0785. -   Parentage:     -   -   Female, or seed, parent.—Kalanchoe blossfeldiana cultivar             Celine, disclosed in U.S. Plant patent application Ser. No.             10/654,563, now abandoned.         -   Male, or pollen, parent.—Kalanchoe blossfeldiana cultivar KJ             2001 1858, not patented. -   Propagation:     -   -   Type cutting.—Terminal cuttings.         -   Time to produce a rooted young plant.—About two weeks.         -   Root description.—Numerous, fine, fibrous, and             well-branched. -   Plant description:     -   -   Form.—Upright plant habit with numerous compound cymes;             freely flowering. Actual plant shape will depend on whether             or not plants are pinched (apical terminals removed).         -   Branching habit.—Freely branching. Pinching (removal of             terminal apex) is not required but will enhance lateral             branch development.         -   Plant height at flowering.—About 24 cm.         -   Plant diameter at flowering.—About 20 cm.         -   Foliage description.—Arrangement: Opposite, simple. Size:             Leaf size is reduced after floral induction. Vegetative             plants: Length: About 9 cm. Width: About 5.5 cm.             Reproductive plants: Length: About 4 cm. Width: About             2.5 cm. Shape: Elliptic. Apex: Obtuse. Base: Obtuse. Margin:             Crenate. Aspect: Slightly concave. Texture, upper and lower             surfaces: Glabrous; leathery; succulent. Color: Developing             and fully expanded foliage, upper surface: 147A. Developing             and fully expanded foliage, lower surface: 137B. -   Flower description:     -   -   Flower type and habit.—Double flowers arranged in compound             dichasial cymes that arise from leaf axils. Upright             flowering stems. Freely flowering.

Time to             flower is primarily dependent upon temperature and light             intensity.         -   Flower opening.—First flower open is the terminal flower at             the main axis and is followed by the opening of the terminal             flowers of the side branches of the inflorescence. About one             week after the first flower has opened, 15% of the remaining             flowers are open.         -   Post-production longevity.—Plants of the new Kalanchoe             maintain good leaf and flower substance for about five weeks             under interior environmental conditions.         -   Flower diameter.—About 1.2 cm.         -   Quantity.—Freely flowering, potentially about 300 flowers             per plant.         -   Flower buds.—Shape: Narrowly oblong.
